对于基于GWT的iOS和Android应用程序开发,我遇到了两个选择:
有人成功整合了其中一个或两个吗?你知道什么是利弊吗?
谢谢.

例如:Touch4j不支持Firefox,因此如果您在Windows中使用GWT进行开发,则无法以开发模式查看应用程序(Safari或Chrome for Windows没有GWT插件)
我正在使用Phonegap 3.0和XCode 5,并试图在我的iOS7应用程序中使用条形码扫描器

我通过从github下载项目的zip并安装via来添加到项目中
phonegap local plugin add /dev/BarcodeScanner-master

但是当我试图从XCode 5运行时,我得到了
Undefined symbols for architecture armv7s:
"_OBJC_CLASS_$_CATransaction", referenced from:
objc-class-ref in CDVBarcodeScanner.o
ld: symbol(s) not found for architecture armv7s
clang: error: linker command failed with exit code 1 (use -v to see invocation)

这个错误似乎与armv7s架构有关,但显然我无法将其关闭,因为我正在构建iOS7.
有人设法让这个(或任何其他)条形码阅读器与Phonegap 3和iOS7一起使用吗?
感谢:D

我有这样的代码嵌入机器人的使用直接行API,而不是通常的iframe实时聊天,但是当我把我的directline私有密钥,机器人占据整个网页.我需要它显示在网页的右下角,当用户点击它时弹出为生活聊天.请有人指导我实现这一目标.谢谢
我在iPhone上为Phonegap集成了一个barcodescanner-plugin时遇到了麻烦.我从这个github存储库获取了我的插件:

我按照说明中的所有步骤操作,包括将所有相关源添加到项目的构建路径的步骤.我也关闭了自动引用计数.我认为每个文件都在正确的位置,但无论如何我遇到了这个错误:
